Asthma

OverviewIf you frequently experience shortness of breath or you hear a whistling or wheezy sound in your chest when you breathe, you may have asthma — a chronic condition that causes inflammation and narrowing of the bronchial tubes, the passageways that allow air to enter and leave the lungs. If people with asthma are exposed to a substance to which they are sensitive or a situation that changes their regular breathing patterns, the symptoms can become more severe.According to the latest WHO data published in may 2014 Asthma Deaths in Malaysia reached 1,642 or 1.29% of total deaths. The age adjusted Death Rate is 8.22 per 100,000 of population ranks Malaysia #58 in the world. and are one of the leading causes of absences from work and school. Asthma often runs in families; according to the World Health Organization, about half the cases are due to genetic susceptibility and half result from environmental factors. Although there is no cure for asthma, effective treatments are available. Asthma can be best managed by seeing an allergist.There are two types of asthma: allergic (caused by exposure to an allergen) and nonallergic (caused by stress, exercise, illnesses like a cold or the flu, or exposure to extreme weather, irritants in the air or some medications).

Asthma Symptoms

Coughing

Shortness of breath

Chest tightness

Wheezing (a whistling or squeaky sound in your chest when you breathe, especially when exhaling)

Asthma Triggers

Outdoor allergens, such as pollens from grass, trees and weeds

Indoor allergens, such as pet dander, dust mites and mold

Certain drugs and food additives

Irritants in the air, such as smoke, chemical fumes and strong odors

Colds, the flu or other illnesses

Exercise (although people with asthma can benefit from some exercise)

Stress

Weather conditions, such as cold air or extremely dry, wet or windy weather

Asthma Management and TreatmentPrevention of symptoms is the best strategy. A person with asthma should know what situations trigger an attack and avoid them whenever possible. If asthma attacks are severe, are unpredictable or flare up more than twice a week, consultation with an allergist can help to determine their cause and provide long-term treatment that controls or eliminates the symptoms.

Asthma Facts and FiguresStudies show that people with asthma who see a specialist, such as an allergist, reduce their:

Symptoms

Emergency room visits

Hospital stays

Visits to the doctor because they are sick

Missed days from work or school

Health care costs

If asthma is left unmanaged or is misdiagnosed, it can be deadly:

Asthma is among the most common chronic childhood illnesses, accounting for 10.5 million missed school days a year. It also accounts for 14.2 million lost workdays for adults.

Every year, about 14 million Americans see a doctor for asthma. About 1.4 million patients visit a hospital outpatient department for asthma; almost 1.75 million go to a hospital emergency room.

The number of people in the U.S. diagnosed with asthma is increasing. The greatest rise in asthma rates is among black children, with an almost 50 percent increase from 2001 through 2009.

Researchers estimate asthma-related costs, including the direct cost of health care and indirect costs such as decreased worker productivity, at around $60 billion annually.

Many people with asthma manage the condition well and can live a healthy and productive life by avoiding triggers and following their allergists’ instructions. If left unmanaged or misdiagnosed, asthma can be fatal; about 3,300 people die from it annually.
